FRANCIS J, MccA1vN, or EDMONTON, ALBEnrmIcanAnA, assrerron rro HEART- s'rooxnn COMPANY LIMITED SHOCK-romaine MACHINE Application filed January 4, 1929. Serial No. 330,293.

This invention relates to a machine for shocking grain inthe field as it is delivered from a harvester and binder towhich the -machine is attached'and more particularly to means for depositing and evenly distributing sheaves of grain in a receptacle in the machine. I

Heretofore in machines of'the type herein disclosed the sheaves of grain have been con- 1 veyed from the binder to the shock former by means of elevators-in'the form of an endless conveying chain or belt. However the method hasrbeen found objectionable in that the sheaves tend to bunch and pile up in the receptacle directly below the point of discharge from the conveyor.

It is therefore an object of the invention to provide a device for distributing the sheaves in a receptacle in the machine without employing the usual elevator, this result being attained by the use of a cradle and a novel mechanism for operating the same;

A furtherobject of the invention is to provide means for evenly distributing the sheaves in a bin or receptacle so that the capacity of the bin or receptacle may beefliciently utilized I A further object of the invention is the provision of a construction and arrangement of parts which enables the sheaves or bundles to be deposited in shoclrformation with the least amount of tractive edort thus reducing the tendency to retard the forward 7 movement of the machine. I

These and other objects are attained bythe novel construction, combination and arrangement of parts hereinafter described andv shown in theaccon'ipanying drawing constituting a material part of this disclosure in so which: 1

V p

At the forward end of the machine'and carried bythe main frame 1 is a trough having a vertical sidewall 2, and an inclined wall 3 the, trough being 'adapted'to receive bundles or sheaves as they are ejected from the binder (not shown). The wall 2 acts as a back plate for the bundles while the lower inclined wall 8 enables the easy entrance of the bundles from the binder. v 1

Attached to the frame 1 are vertical struts 4, 5, whichsupporta horizontal member 6, the latter having its rear end inclined upwardly at 7 as'shown in Fig. 1 to serve as a support for mechanism used in the operation of a tilting receptacle. The structure of the receptacle and the-mechanism referred to form no part of this invention. A cross bar 8 connects'the frame member 1 to a frame member-9 inclined thereto, the

'frame structure being further strengthened by the members 10, 11. Attached to members 10 and 11 are upstanding bearing supports 12, 13 upon which is pivotally mounted a bin or receptacle 15, the latter being normally open at the top toallow the introduction of bundles or sheaves.

Fixed to supports 1,4 'respectivelyare bearings 16 and 17, in which is journalled a shaft 18 (see Fig. 5). Attached intermediate of shaft 18 is a casting 19, in which is journalled a vertical shaft 20, the lower. endof '85 which shaft is attached to an arcuate brace 21 of acradle.

The cradle comprises a plurality of arouate braces similar to brace 21, upon which are positioned a plurality of wooden slats 22, the forward'end of the cradle beingprovided with an end plate 23, (see Fig. 1). The cradle is normally positioned in the trough between the walls 2 and 3 so that it may receive bundles from the binder. 9

Referring again to Figures 8 and5, the. Q shaft 20 has fixed thereto, intermediate of its length, a pair of brace bars 24, 25 which are also fixed to sides of the cradle.

1 Attached to a collar 26 connected with the 100 arcuate brace 21 and shaft 20 is a link 27, which is fiXed to arm 28 of rockshaft 29, the latter passing through an aperture 30 in wall 2 and being journalled in bearings 31, 32 supported by frame members 1 and 10.

Fixed to shaft- 29 is a gear 33 which meshes with a segmental gear 34, the latter being nonrotatably mounted on a stub shaft 35 jourialled in a bearing 36 mounted on support 4. A crank arm 37 is fixed to shaft 35 and pivotally connected to a link 38, which in turn is pivotally connected to a crank arm 39, fixed to shaft 40, the latter being journalled in bearing 41 on frame member 1. The shaft is keyed to the male member 42 ofa clutch upon which is pivotally mounted a rocker member 45. comprising an arm 46 and an engaging roll 47, (see rigures 6, 7) which is normally urged into engagement with the female clutch member 43 by a compression spring 44 bearing against the rocker member 45 and a hub integral with the male member 42.

The rocker arm 46 projects beyond the periphery, of male member 42 and is adapted to engage an arm. 48, which is connected to a rock shaft 49 ournalled on frame member 50, the rock shaft 49 also having a crank arm 51 by which it may be operated.

It will be seen that when the arms 46 and 48 are in engagement, the clutch will be disengaged, and when the shaft 49 is rotated by means of crank arm 51, to break the engagement between the arms, the spring 44 will cause the engagement of the male and female clutch members.

The periphery of the female member 43 is provided with sprocket teeth 52 in engagement with a chain 53, the latter passing over a sprocket 54 connected to the dr've wheel 55 of the machine.

In operation,v when it is desired to discharge bundles from the cradle into the receptacle 15, the male member 42 is allowed to engage the female member 43 of the clutch, which action will cause the drive wheel, through the intermediate mechanism, to rotate arm 39, to pull link 38 forward and rotate segmental gear 34 and gear 33, to rock the shaft 29 and lift the cradle to a position as shown in Figure 1 in dotted lines, to discharge the bundles into the receptacle.

The shaft 40 will be rotated one revolution after which the arms 46 and 48 are again engaged to release the clutch. A spring 56 has one end connected to the frame of the machine and the other end connected to the pivot for link 38 and crank arm 39 to hold the w ight of the link and crank arm to preventthem from falling back and causing the clutch to jerk.

When crank arm 39 is rotated through one revolution, the arm 37 and segmental gear 34 are moved through one third of a revolution and back again to their original positions The gear 33 is moved through two-thirds of a revolution, and the crank 28 raises the cradle through one-half revolution to the position shown in dotted lines in Figure 1, to deposit the sheaves inv the receptacle, and then returns to its initial position. Spikes 57 are carried in the bottom of the cradle to k ep the sheaves in position while the cradle is being raised. (Fig. 4).

In order to evenly distribute the sheaves in the receptacle the cradle swung successively into three positions, to the right, to the center and then to the left. To accomplish this result the following mechanism is employed.

Referring to Figure 5, it will be noted the upper end of connecting rod 20 has fined thereto a crank arm 58, pivotally connected to a link 59, which in turn is pivotally connected to a crank arm 60, fixed to one leg of V a U-shaped member 61, the leg being rotatably mounted in a bearing 62 mounted on the support 63. The other leg of the member 61 is pivotally connected to a link 64, the latter being pivotally connected to a lever 65 pivoted to a cross bar 66 attached to wall 2 and the support 4. Carried by lever 65 is a pair of rollers 67 which engage a cam 68 on a drum 69. The drum 69 is provided at one end with three equally spaced notches 70 adapted to be engaged'by a pawl 71 pivoted to a crank arm 7 2 fixed to shaft 18. The other end of the drum is provided with three equally spaced notches 73 adapted to be engaged by holding pawl 74 pivotally mounted on the adjacent support 63.

From the above description it will be seen that when shaft 18 is rotated clockwise (Fi g. 5) during the return of the cradle to its initial position, the pawl 71 will engage one of the notches 70 to rotate the drum one-third of a revolution, the drum being rotatably mounted on shaft 18. This movement of the drum causes cam 68, through rollers 67, to move lever 65 from extreme right to centre position. During the next one-third revolution of the drum the lever will be moved from centre to extreme left, and so on. The movements of the lever cause similar movements of the U-member 61 to rotate connecting rod 20 in the casting 19, and shift the cradle from left, to center, to right, etc. so that with each depositing operation of the cradle, the sheaves will be deposited in'either the left, centre or right section of the receptacle 15.

lVhen the receptacle has been filled, the sheaves will be discharged therefrom in an upright position on the ground by a mechanism herein shown, but not described, such mechanism forming no part of this invention.

The foregoing disclosure is to be regarded as descrintive and illustratve only, and not restrictive or limitative of the invention, of which, obviously, an embodiment may e constructed including many modifications without departing from the scope herein indicated and denoted in the appended claims.
